Connecting.the.antenna; Connecting An Optional Antenna - Uniden BC125AT Owner's Manual

If your scanner receives interference or electrical noise, move
the scanner or its antenna away from the source. You might also
try changing the height or angle of the rubber antenna.
To improve the scanner's reception, use an optional external
antenna designed for multiband coverage. (You can purchase
this type of antenna at a local electronics store). If the optional
antenna has no cable, use 50 ohm coaxial cable for lead-in. An
adapter plug might be necessary for the optional antennas.
Use an optional mono earphone or stereo headset with proper
impedance for private listening. Read the precautions on the
inside front cover of this Owners Manual.
Do not use the scanner in high-moisture environments such as
the kitchen or bathroom.
Avoid placing the scanner in direct sunlight or near heating
elements or vents.
